by persons with reduced physical, sensory or mental capabilities or
lack of experience or knowledge, provided that they are supervised or
have been instructed in the safe use of the appliance and understand
the hazards involved. Children must not clean or carry out user main-
tenance on the appliance except under adult supervision.
Warning Ensure that children do not play with the product.
Warning The installation must only be carried out by a qualified installation en-
gineer, following applicable rules and regulations in addition to these
installation instructions.
Caution The heat pump must be located in a frost-free environment!
Caution Installation and connection should be carried out in accordance with
the instructions, in order to avoid subjecting local residents to noise
disturbance.
Caution The heating appliance should be placed on a stable surface that can
support the gross weight of the heating appliance.
Caution Before the heat pump is powered, you must ensure that the heating
system and coolant system, including the heating pump, are full and
bled; otherwise, their circulation pumps may be damaged.
Caution If the electrician wishes to test the electrical connections before the
above is carried out, this should only be done after ensuring that the
heat transfer fluid pump and coolant pump are disconnected.
Installation Guide DHP-M
VMJSB202 Danfoss Heating Solutions

Caution When filling the coolant system the coolant pump must be operating;
you must ensure that the compressor and the heat transfer pump can-
not start.
Caution This appliance is intended for use by expert or trained users in shops,
in light industry and on farms, or for commercial use by lay people.
Caution In accordance with EN60335-2-40, this product is classified as "not
available to the general public." This means that the product is de-
signed to be handled by trained staff and installed in an engine room
or similar.
Caution Isolate the power supply to the heat pump while servicing the appli-
ance or replacing parts.
Caution Only spare parts approved by Danfoss Värmepumpar may be used for
this appliance.
N
In normal operation the heat pump generates noise and vibrations.
The appliance should be set up and connected in accordance with the
instructions in order to avoid noise being spread to noise-sensitive
areas.
2.2 Refrigerant
2.2.1 Refrigerant
Caution Work on the refrigerant circuit must only be carried out by a certified
refrigeration engineer.
Although the heat pump's cooling system (refrigerant circuit) is filled with a chlorine-free and environmentally-approved refrigerant that
will not affect the ozone layer, work on this system may only be carried out by authorised persons.
Installation Guide
DHP-M
Danfoss Heating Solutions VMJSB202

2.2.2 Fire risk
The refrigerant is not combustible or explosive in normal conditions.
2.2.3 Toxicity
In normal use and normal conditions the refrigerant has low toxicity. Even though the toxicity of the refrigerant is low, it can cause injury
(or even death) in abnormal circumstances or if deliberately abused.
Warning Risk of personal injury! Spaces in which heavy vapor can collect below
the level of the air must be well ventilated.
Refrigerant vapour is heavier than air, and in enclosed spaces or in areas below the level of the door, for example, seepage can give rise
to high concentrations with a resultant risk of suffocation due to lack of oxygen.
Warning Risk of personal injury! Refrigerant exposed to a naked flame creates a
poisonous irritating gas. This gas can be detected by its odor even at
concentrations below its permitted levels. Evacuate the area until it
has been sufficiently ventilated.
2.2.4 Working on the refrigerant circuit
Caution When the refrigerant circuit is repaired, the refrigerant must not be re-
leased from the heat pump - it must handled appropriately.
Draining and refilling must only be carried out using new refrigerant (for the amount and type of refrigerant see manufacturer's plate)
through the service valves.
Caution All warranties will become void if a refrigerant, other than what Dan-
foss specifies, is used for refilling.
2.2.5 Scrapping
Caution When the heat pump is to be scrapped the refrigerant must be extrac-
ted for disposal. Local rules and regulations related to the disposal of
refrigerant must be followed.

2.3 Electrical connection
Warning Hazardous electrical voltage! The terminal blocks are live and can
cause death through electric shock. All power supplies must be isola-
ted before electrical installation is started. The heat pump is connec-
ted internally at the factory, for this reason electrical installation con-
sists primarily of the connection of the power supply.
Caution Electrical installation may only be carried out by an authorized electri-
cian and must follow applicable local and national regulations.
Caution The electrical installation must be carried out using permanently rout-
ed cables and must follow applicable local and national regulations. It
must be possible to isolate the power supply using an all-pole circuit
breaker with a minimum contact gap of 3 mm.
2.4 Water quality
Caution A normal heating system always contains a certain amount of corro-
sion particulates (rust) and sludge products from calcium oxide. This
comes from acid that is naturally occurring in the fresh water that the
system is filled with. It is not good practice to have to fill the heating
system regularly which is why any leakage in the heating system
should be repaired immediately. Normal filling should occur only once
or twice a year. The water in the heating system should be as clean as
possible, always position the dirt filter on the return line from the heat-
ing system to the heat pump, as close to the heat pump as possible.
Caution Hard water; Normally it is not a problem installing a heat pump in
areas with hard water because the normal operating temperature for
the hot water does not exceed 60°C. In areas where there are excep-
tional prevailing conditions with the water one can install a softening
filter, which softens the water, cleans any impurities and prevents the
build up of calcification.

3 Transport, unpacking and setting-up
3.1 Transporting the heat pump
Caution The heat pump must always be transported and stored upright in a
dry environment. Secure the heat pump so that it cannot tip over dur-
ing transportation.
Caution If the heat pump is laid on the incorrect side it may become seriously
damaged, as the oil in the compressor may run out into the pressure
pipe and thereby prevent normal functioning.
3.1.1 Unpacking
1. Check that there are no transportation damages.
2. Remove the packaging.

3.2 Setting-up the heat pump
3.2.1 Recommended location
Positioning the heat pump
The heat pump should preferably be placed against an outside wall (see chapter 'Heat pump data')
Do not place the heat pump against walls facing noise-sensitive areas.
Avoid placing the heat pump in the corner of a room.
Installation Guide
DHP-M
VMJSB202 Danfoss Heating Solutions

If possible, choose a location where the surfaces nearest the heat pump are soft. Avoid placing the heat pump close to large plas-
tered or tiled areas.
The heat pump is fitted with internal vibration insulation. However, the degree of vibration insulation achieved depends on the
bearing strength of the surface the heat pump stands on. In order to achieve adequate vibration insulation, the heat pump should
be placed on a concrete floor with a thickness of at least 100 mm, or another surface with equivalent characteristics.
In order to minimise noise generation from the heat pump, the sound plate (included) should be fitted when the heat pump has
been put into position.
The heat pump must be level.

6 Piping installation
Caution To prevent leaks, ensure that there are no stresses in the connecting
lines
Caution Pipe installation must be carried out by an authorised installer
Caution Ensure that the pipe installation is carried out in accordance with the
dimensions and connection diagrams
Caution Bleed valves should be fitted if necessary
6.1 Safety valves
Warning Radiator systems with a closed expansion tank must also be equipped
with an approved manometer and safety valve. The safety valve
should be to a minimum of DN 20 and have a maximum of 6 bar open-
ing pressure, or according to country-specific requirements.
Warning The overflow pipes from the safety valve must not be closed off. The
pipes should discharge into an outlet in a frost-free area.
Warning The connecting pipe between the expansion tank and the safety valve
must slope continuously upwards. A continuous upwards slope means
that the pipe must not slope downwards from the horizontal at any
point.
Caution Cold and hot water pipes and overflow pipes from safety valves must
be made of heat-resistant and corrosion-resistant material, e.g. cop-
per.

6.2 Heating system supply pipe and return pipe
Install a filter (max mesh size 0.7 mm) in the heating system's return pipe to protect the unit against foreign particles.
Install the supply line with all the accompanying components.
Ensure that the correctly dimensioned system pump is connected to the heating system's supply line, and connect the system
pump's control cables to the correct terminal block (see connection of system pump).
Install the return line with all the accompanying components.
Insulate the supply and return lines.
6.3 Noise information
To prevent disturbing noise from the heat pump the following recommendations should be observed:
The heat pump's pipe connections cause vibration. In order to prevent this vibration spreading to the heating system and frame,
the pipes should be connected and laid with particular care.
The brine and heat transfer fluid should normally be connected to the heat pump by means of a flexible hose.
Pipes must not be attached to walls facing noise-sensitive areas.
In cases where attachment of pipes to sensitive construction elements cannot be avoided, special elastic pipe attachments should
be used.

6.4.1 Drill holes for brine pipes
Caution Ensure that the holes for the insert pipes are positioned so that there is
room for the other installations.
Caution The brine pipes shall have separate lead-ins. If the wall lead-ins are be-
low the highest ground water level watertight lead-ins must be used.
The brine pipes must be insulated from the heat pump, through the walls and outside the house all the way to the collector so as to
avoid condensation and prevent heat loss.
If the brine pipes are to be routed above ground, drill holes in the walls for them.
